My invention relates to that class of winding machines wherein cords or yarns, for instance, such as are useo in'carpet weaving, are wound from separate bobbins onto a common spool, the ends of each yarn being kept separated from the ends of the other yarns, so that they will be in proper position when the spool is used in connection with theloom; and objects of my improvements areto increase the'accuracy with which the length of the threads of the yarn wound on a particular spool is measured; to provide means which will prevent winding too much or too little yarn upon a spool; to provide means whereby the reed in which the outer ends of the yarns are locked in position may not be locked to the yarn except when the correct amount of yarn has been wound upon the spool; and to accomplish such results by the use of novel'mechanical appliances hereinafter described.

A side plate 1 carries thereeds andtheir operating mechanism. A similar plate is located at the other side of themachine.v A bobbin 2 furnishes a yarnv 3, which passes through the fixed reed 4: and onto the spool 5 upon which it is wound. are old and well known .inthe art, and I have, therefore, omitted the conventional framework in which they are mounted. and the driving mechanism, for the spool, and. the multiplicity of bobbins. For those familiar with the art fully understand the general setting and arrangement of the parts illustrated. i

Behind the reed dis a locking reed 6, which is shown as consisting of a bar element 7,

in which a set ofpins 8 are mounted. These pins 8 cor-respond with the pins of the reed i.

The reed 6 lies in a groove 10 in a carrier 11, which is provided with lugs 12 passing through slots 13ina webiplatel lc disposed between the side plates l', 1, of the machine, and held therein by suitable means, such as headed bolts 15, 15. This arrangement. allows the carrier 11 to be raised andlowered, which may be done by means of the; hand hold 16, which swings the pivot cams 18, 19, connected by rod 17, to raise thecarrier 11. The carrier will drop again of its own weight.

The reed 6 is provided at each end with a spring 21, which springs serve to hold in place a cap .22 which may be used to lock the reed 6 to the yarns, as will be hereinafter explained.

A'roller 23, preferably having aroughened surface as 24:, formed-bywinding emery paper or the like around the roller, rotates freely in bearings carried by the side plates 1, 1, so that as -the yarn from the bobbins, passing through the reedt and over the roller 23, is drawn forwardby thespool Sand wound on it, the roller 24 is rotatedzby the friction of the yarn.

{)n the shaft 25 of the, rollerv 23 is mounted a clutch element 26, having sockets 27, 27,

These elements machine.

adapted to cooperate with a spring pressed pin 28 carried by a worm 29. The worm 29 is mounted loosely on the shaft 25.

Above the worm 29 is mounted a worm gear 31 carrying a cam race 32. The worm gear 31 is mounted on ashaft 33 carried by an arm 34 attached to the framework of the Rigidly mounted on the arm 34, and cen- 'tered about the shaft 33, is a dial element 35,

' the worm gear 31 is turned backward.

The position of the stop 42 corresponds with the high point 43 in the cam race 32.

So'that the distance which the worm wheel 31 shall rotate forward before the high point in the cam race 43 reaches a given position may be controlled by the position of the adjustable stop 37 In the cam race 32 travels a roller44, carried on the end of an arm 45 pivoted to the side plate 1. To the upper part of the arm 45 is pivoted a connecting bar 46, which in turn is pivoted toward one end of a lever 47 swinging on a pivot 48 anchored to the framework of the machine. The lever 47 has an arm 49. adapted to swing forward over the end of the carrier 11, and to be rocked backward from over the carrier by the rotation of the cam race 32.

To the upper end of the lever 47 is attached a plate 51 provided with a hole 52.

The bracket 54, secured to the side plate 1, has an upturned end 55, through which slides one end of a pin 56, the other end of which is pivoted to one arm of a rocking bar 57, carried by-a pivot pin 58 secured to the end plate 1 The. other arm of this rocking bar 57 is connected through links 59, pivot bar 61 and link 62, to the free end of a clutch lever 63, which is also pivoted on the pivot 58, and is provided at itsother end with fingers 64. 65, adapted to engage against the. opposite sides of the worm29, so that the worm 29 ma 7 be shoved out and in on the shaft by the swinging of the arm 63.

The operation of the machine is as follows.

The preliminary adjustment consists in turningthe roller 23 backward or forward untilthe high point in the cam groove 43' is reached by'the roller 44 on the arm 45. This results in swinging the bar 46, and through it the lever 47, so that the hole in the 1 plate 51 registerswith the free end of the pin 56. This allows the lever 63 to beswung connect it from the worm gear 31. In this operation the end of the. pin 56 is slid through the hole 52 in the plate 51, and beyond it, space being provided to accommodate this movement of the pin. This looks the lever 47 against movement.

The yarns having been carried from the bobbins through the reed 4, over the roller 23, and secured to the spool 5, the length of the yarn to be'wound on the spool is decided upon and the stop 37 is adjusted to the proper position on the scale 41 of the dial 35.

The worm' gear 31 is then turned backward until its stop 42 encounters the stop 33 on the dial. 'This reverse movement of the worm gear 31 reverses the movement of the lever 63 and its connections, so that the pin 56 releases the plate 51 and allows the arm 49 of the lever 47 to be swung forward over the end of the carrier 11, as shown in Fig. 3. This looks down the carrier, which can not be raised unless the arm 49 is withdrawn.

This same movement reconnects the clutch elements between the worm 29 and the clutch 26, the plurality of pin sockets in the clutch allowing this connection with a minimum of waste motion.

The spool may now be set in motion and the yarn wound upon it, the drag of the yarn over the roller 23 turning the roller, and through it the worm 29 and worm gear 31, during which movement the arm 49 will remain in the locking position above the carrier 11 so that the carrier can not be raised, until the roller 44 reaches the high point of the cam race 32, when, by the movement of the lever and bar 46, the lever 47 will be swung back so that its arm 49 is withdrawn from above the carrier 11. At this precise spot the machine should be stopped, as the proper length of yarn will have been drawn past the reed 4. The hand hold 16 is then pulled out, causing the cams 18, 19 to raise the carrier 11 so as to bring the reed 6 up against the yarns and to thrust its pins 8 up between the yarns. The cap or cover'22 is then snapped down from above, between the springs 21, 21, over the pins 8, 8, soas to grip or look the yarns fast to the reed 6. The carrier 11 isallowed to descend, and a new reed 6 is slipped into it in proper position. The clutch is thrown out, releasing the worm from y the worm gear, and the worm gear is turned back to its initial position, with its stop 42 against the stop 37. The clutch is thrown in again. The machine is then started "again,

the yarn carrying the reed 6 forward with-it until it reaches the spool, when the machine is again stopped.

The spool is drawnbackward sufficiently I to allow the insertion of a new spool in front of it, in the well known manner, and the yarns are fastened to the new spool as bythe usual fastening rod. Then the yarn is cut so as to slide the worm 29 outward and dis- 1 'Is o the reed attached to it is withdrawn. The winding of the new spool is then proceeded with until the high point of the cam race is again reached, when the above described process can be repeated.

If the operator attempts to raise the carrier so as to attach the reed 6 to the yarns before the proper length of yarn has passed the reed, that can not be done, because the cam race 32 prevents the swinging of the arm 45, bar 46 and lever 48, so as to free the carrier and allow it to be raised. Furthermore, if the operator allows the high point of the cam race to pass before stopping the machine the reed 6 can not be raised, for, although the arm 49 was thrown back out of locking position by the passage of the high point of the cam race, yet it was immediately swung back again into locking position so as to prevent the raising of the carrier 11. The action of this cam should be quick, so that there shall be no extended period during which the carrier 11 can beraised. For the ultimate object of my improvements is to prevent the careless measuring of the yarn, by the winding of too much or too little on the spool, which is asource of considerable loss in practical manufacturing under present condi tions. The pitch of the cam shown in the drawings, in the race 32, is therefore to be considered as generally indicative of a cam, but not accurate in proportion, as the precise pitch of the cam necessary to obtain the results I have indicated may be readily determined by the practical mechanic in constructing the apparatus.

I desire it to be understood that the apparatus which I have depicted is intended to be an illustrative, but not an exclusive, type. For it will be well understood that details of construction may be modified as by the use of mechanical equivalents without departing from the spirit of my invention as claimed.
